Message 1403332 - Posted: 15 Aug 2013, 6:34:20 UTC - in response to Message 1403276.  

As of Aug 14, since Dec 2013 I have PM'd all of the 103
hosts I noticed (via Inconclusive results vs my
results) are producing
bad results.
Many days I don't have time to look, of course.

A small percentage of all Seti hosts, but makes me wonder
how many there are that behave badly. Hopefully the science
will not suffer.

Far to many sadly and SETI V7 might have cured the nvidia '6xx problem, but it also seems to have caused a lot of once reliable rigs to go rogue though at least now there is a system in place to limit them (sadly there are still a few slipping through the cracks here and there).

Cheers.

PMed MiklaDfar about his host 6971106 which throws a lot of invalids and errors, and all of the work on the GPU is validation inconclusive.

Impossible to PM, since it's an anonymous user, but a system to keep an eye on: http://setiathome.berkeley.edu/results.php?hostid=5940769

The amount of errors (11) and invalid (914) far outweigh the valid (27).

A contributor (not named here)
with a bad host replied to my request s/he deal with
the host issues
Validation inconclusive (192) · Valid (100) · Invalid (89) · Error (283)

in the following response to my PM:
--------------
I don't know exactly what I would do to fix the machine since there's absolutely nothing wrong with the machine?

This would have to be some issue with their software and Windows 8 or something else period.

This system has absolutely no issues what so ever in operation etc. and my main machine for everything I do.

Never had a BSOD, errors, anything period. Work, Gaming, etc. never a hiccup.

BOINC has had failures not just for me but many others when you look at the errors that do appear in the application for units.

Google BOINC Computational Errors. It will keep you reading forever.
--------------- end user response
Note that the Error tasks clearly show error reports like
(unknown error) - exit code -1073741819 (0xc0000005)

Will the owner do anything? Who knows?

I've received those a few times even when I've given them the fix for their problems. :-(

But most will not reply at all.

(not named here) got back to me again and explained how he is
a windows expert and administrator for 20 years
and the machine has nothing wrong with it.
Meaning, I guess, he wants to keep processing
Seti and getting errors and Invalids as his primary results.

(not named here) writes in a pm today:

"The errors are for debugging and used so that they can perfect the software.

...

Nothing failed or invalid affects Seti in any way it's simply my PC and it's processing time wasted. The units go out to multiple folks and the numbers crunched when any fail or are invalid they simply go to the next guy.

If I were to produce one good unit return out of a thousand - that's a good return. This is why I would only get one credit for the one return."

Uhhh. Wow. 1 valid of a 1000 tasks is ok with this person.

It's good to see that the 1st 1 has had the screws put on it now as that rig had over 11K tasks in progress a week or 2 ago.

But sadly there are many, many more just like these 2 around these days. :-(

[edit] Here's my post about that rig from back on the 10th of this month and then that rig had over 14K tasks in progress. :-o [/edit]

Cheers.

When people in other BOINC projects deplore the lack of a GPU version I tell them: go to SETI@home and see what is happening there.

And another one to keep an eye on. I've crossed paths with this one several times now (outside the two times showing in my results). Too bad its owner wants to be anonymous. Wouldn't you notice it that your dual GTX 560 Ti has to have a higher RAC than 'just' 2,600?

Message 1408742 - Posted: 28 Aug 2013, 8:37:45 UTC - in response to Message 1407153.  

Actually if I posted another list of the bad rigs that have annoyed me again, it would be at least 3 times bigger than what my last 1 was under SETI V6.

Thankfully 99.9% of those are now being tightly restricted, but it's a shame that those limits couldn't have been implemented under SETI V6 (when the GT/X 6xx series came out) so that V7 (and latter AP V6 apps) could've had a few more bugs worked out before being release to the general public.

Cheers.

Wiggo, how do you determine that rigs "are being tightly
restricted"? The "In progress" State value or something else?
What number exactly means "tightly restricted" to you?

I have a list of over 100 hosts that have behaved badly and wonder
what fraction meet your restricted category.
Thanks.

The "In Progress" has a bit to do with it, but a long time of observations has a lot more to do with it.

Just look at those out of control rigs with GTX560's from SETI V6 that were just trashing work by the hundreds and are still trashing work under SETI V7, but now these rigs only get a very limited opportunity to trash work now.

Cheers.

BTW the other way is that I don't have the hundreds of "Validation inconclusive" that I use to, which was caused by these crappy rigs running out of control.

Now my best rig hasn't had better than 40 "Validation inconclusive", but it doesn't get over the fact that there are more bad rigs out there than there use to be (a lot used to be good, but under SETI V7 they have turned bad).

Cheers.

This rig has been a problem since at least last October (maybe even April but I can't find the posts atm), but it's listed in my post here back in May, http://setiathome.berkeley.edu/forum_thread.php?id=71767&postid=1372932 and marked as "long term" back then (I use to put out a bad rig list about every 6 months) so I can tell you that I've had no response to repeated PM's from this person.

But then that person is down to about a 1 third to 1 quarter of the amounts that they use to produce.

Cheers.

PM'ed owner of host 6359587 which is producing a lot of invalids, and whose pendings will most all be going to the invalids list soon.

One weird thing about his Application Details that I don't understand:

SETI@home v7 (anonymous platform, ATI GPU)
Number of tasks completed 1
Max tasks per day 33
Number of tasks today 274
Consecutive valid tasks 0
Average processing rate 4980.8622641511
Average turnaround time 0.17 days

How can his number of tasks today be so high, when his max tasks per day is only 33?
